Dear Ms. Samaporn,
thanks for your mail, my itinerary is a little bit irritating. It is provided that I’m departing Frankfurt at 14th September 22:00 o’clock and am arriving at 14:10 o’clock at 15th September. This is expressed by 14:10+1. +1 means plus 1 day. Conclusion: I need accommodation for 5 nights beginning from 15th September.
